To a whom it may concern:

Be it known that I, EMERSON C. GLATFEL- TER, a citizen of the United States, residing at New Philadelphia, in the county of Tuscarawas and State of Ohio, have invented certain new and useful Improvements in Machines for Forming Concrete Blocks; and I do hereby declare that the following is a full, clear, and exact description of the same, ref- [0 erence being had to the annexed drawings, making a part of this specification, and to the fi ures ,of reference marked thereon, in w rich- Figure 1 is a perspective'view. Fig. 2 is a view showing the bottom or under side of the machine, showing the legs in cross-section; Fig. 3 is a vertical section taken on line 3 3, Fig. 2. Fig. 4 is a detached view of the hoper. Fig. 5 is a view showing a finished 2o iilock. Fig. 6 is a view showing portions of one of the hinged end plates and side plate, showing one pivoted arm upon each of said end-and side plates. Fig. 7 IS a detached view of the lifting-head. F ig. 8 is a detached perspective view of the bearing-sleeve.

The present invention has relation to concrete-forming machines; and it consists in the novel construction hereinafter described, and particularly pointed out in the claims.

Similar numerals of reference indicate corresponding parts in all the figures of the drawmgs.

in the accon'ipanying drawings, 1 repre sents the supporting-legs, which support in proper elevation the. bed-plate l, which hedplate is provided with the open recesses 3,

' which open recesses are for the purpose of receiving the pivoted arms 4 and 5, which pivot-ed arms are securely fixed in any conven- 40 ient and well-know n .n'ianner to the side plates 6 and the end plates 7, which plates when brought into a vertical position constitute and produce a structure, or what might oied arms 4 and 5 are each extended down- -weird and below the bottom edges of the plates 6 and 7 and are pivotally connected to the flanges 8 or their eq uivalcots. To the extreme bottom or lower ends ofthe pivoted arms 4 and 5 are coi'niected the bars 9 and 10, it being understood that there are two sets of end plates. The bottom or under side of the 5 5 bed-plate 2 is provided with the bearing 11, which bearing is preferably screw-threaded at its bottom or lower end to receive and hold the nut 12. Upon the bearing 11 is loosely mounted the sleeve 13, the upper end of which is provided with the head 14. To the sleeve 13 "areattached or formed integral therewith the bars 15 and 16, which bars are located at right angles to each other and are for the purpose hereinafter described. To the ,bar 15 is ivotally attached the operatingrod 17, which rod is extended under the bedplate 2 and beyond the end thereof, and to the outer end of said rod is pivotally attached the bottom or lower end of the operating-le- 7o ver 18, which operating-lever is pivotally attached to the flanges 19or their equivalents a short distance above the bottom or lower end of said operating-lever. .To the bars 16 are pivotally attached the links 20, which links are connected to the end-plate bars 10. To the bars 15 are attached the links 21, which links are pivotally attached to the side-plate bars 9, said parts being assembled and arranged as best illustrated in Fig. 2, and as arranged in said figure when the lever 18 is moved inward the bottom or lower end of said lever will be moved outward, which by means of the links 20 and 21 will move the. plate-bars 9 and 10 inward and of course oscillate or rock the arms 4 and 5 and move the end and side plates outward, after which the block can be removed, as hereinafter described. By an outward movement of the lever 18 a reverse. movement of-the parts operated by said lever is brought about, which reverse movement places the side and end plates in position to mold or form a block. For the purpose of holdingthe side and end plates in any desired adjustment, either open 9 5 or closed, the rack-bar .22 is provided, which is held in fixed position-and provided with a. be termed a box/ of the shape and size of i '45 the block designed to be formed. The pivseries bf notches 23, which series of notchesreceive the extended flanges :34, formed upon the lever 18.

I t is well understood that in forming blocks of concrete various si '"ed and shaped blocks are required, and for the purpose of providing means for clanging the side and end plates and at the same time adjusting said plates in or out the flanges 8 are provided with a series of apertures 25, which series of apertures are "bars 9 and 10, or four distinct and separate bars, two forthe side plates and two or the for the purpose of changing the position of .J... New

formed in the bottom of the bed-plate 2, and

the top of the head 14 and the nut 12 turned so as to take up any slack between the head 14 and the bed-plate 2, thereby insuring a true movement of the head 14, together with the bars 1.5 and 16.

F or the purpose of providing adjustment as between the bars and 16 and the various plate-bars 9 and 10 the links and 21 .are provided with a series of apertures 29,

' son of the which a ertures are for the purpose of receivin the )olts 30. it being understood that the ho ts are to be placed through the proper aperture of the series of apertures 29 to bring a out the desired adjustment for the varioussized blocks.

For the purpose of providing an eans for allowing the bars 9 and 10 to move back and forth, so as to tilt the mold walls -or plates 6 and 7, the bottom or lower ends of the pivoted arms 4 and 5 are pivotally connected to said bars 9 and 10 by means of the bolts 10, by which arrangement there is a pivotal connection between the links 20 and 21, the bars 9 and 10, and the mold-plates 6 and 7 by reaivotal connection of the lower ends of the pivoted arms 4 and 5. It will be understood that no pivotal connection is necessary as between the bars 9 and 10 and the links 20 and 21 except in' a horizontal plane,

and the horizontal pivotal connection is made by means of the apertures 29 and the bolts 30. The follower or false bottom 31 is laced upon the top or upper side of the bed-p ate2, as illustrated in Fig. 3, which receives the lastic material from which the block is to be ormed, and if it is desired toform openings in the block, such as shown in Fig. 5, or of any other desired form, the cores 32 are provided, which cores are held in proper position by means of the lug-bolts 33. After a block has been )IO erly Formed and it is desired to remove t e lock the side and end ,plates 6 and '7 are thrown outward, as illiistratcd indotted lines, Fig. 3, after which the follower 31 is moved upward by an upward movement of the rods 34, which rods pass through the apertures 35, formed in the bed-plate 2, and come in contact with the bottom or under side of the follower 31. The rods 34 are socurely connected to the spider 36, which spider is connected to the reciprocating rod 37, which rod is located in the hollow standard 38, .but is formed of a length less than the is pivotally attached to the bracket 40 or its equivalent, and extended outward for the purpose of bringing it into position to be operated and at the same time produce the desired amount of leverage.

It will be understood that a downward movement of the lever 39 will elevate the rod 37, together with the different parts carried thereby, and when so elevated the follower 31 will be moved upward, carryingwith it the finished block, after which the block can be easily removed.

For the purpose of holding the follower in elevation one of the legs 1,0r its equivalent, is provided with a series of notches tl, which notches receive the lever 39 and hold the lever against displacement.

It will be understood that when the follower is placed upon the bed-plate 2 the lever 39 should be locked against a movement, and

to so look :the lever the notches 42 are provided.

For the purpose of bringing abouta true reciprocating movement of the rod 37 by the movementof the lever '39 said legver is provided with the slot 43, througli which slot is located the pin 44, which pin is securely connected to the reciprocating rod 37.

4 For the purpose of assisting in elevating the follower, together with the block carried thereby, the spring 45 is provided. which spring is located below the reciprocating rod 37, and of course when said rod is lowered the spring will be compressed, and the energy of said spring will be exerted when thelever 39 is freed to be moved to elevate the follower.

In the formation of blocks for buildings it is sometimes desirable to bevel or notch the corner or corners of a block for the. purpose of providing for timbers, such as rafters, and in order to so form blocks I provide the detachable block or former 46, which is provided with the hooked flange 47, which hoplged flange is designed to be connected to the top or u per side of the side or end plates, as desired: reference being had to the particular point where the beveled portion is to be located. i

' For the purpose of providing moans for placing the plastic material in the former proper the hopper 48 is provided, which bopper is dctachably cmmectcd to the side and end plates 6 and 7 by means ol' the springs 1 1i and of course is tobe removed alter a sullicient amount of plastic material has been placed in position to properly l'orm or mold a given-sized block.
